I would have more confidence in Castrol products over Penzoil. After nearly 50 year working on engines, the cleanest engines even with very high mileage all ran Castrol oil and changed the oil at reasonable amount of miles. The dirtiest engines I have worked on use Penzoil, was very common to have a heavy waxy build up and many times oil galleys were severely plugged up
